A1c 9.1 → 5.4 over 14 months, full table inside

Explainer Receipts ×7

A1c 9.1 → 5.4 over 14 months, full table inside, which sounds obvious until you try to state the evidence for it.

Since the title puts numbers in the shop window: 14 months.

Different laboratories use different assay platforms with different calibration. Comparing across labs adds a systematic offset that is invisible on the report.

Time of day, fasting state, hydration and recent exercise all move common markers. Standardising the draw conditions is free and it removes most of the apparent variability.

Screenshot none of this. Read the whole thread, including the parts where I am told I am wrong.

Nobody here can interpret your panel and this comment is not doing so. What a board can usefully do is help you ask better questions of somebody who can.

Agreed on assay changes. A lab switching platforms between your draws is invisible unless you ask.

Tracked hs-CRP against the weight trend for a year. The correlation was much weaker than I expected and that was worth knowing.

Small fix — a reference interval is not a treatment target, and the post above uses them interchangeably.

What did the repeat show?

Left up. It is a question about how to compare panels, not a request for interpretation.

Compared two draws across two labs and spent a week worrying before finding out the assays were different.

Substantial weight loss independently moves lipids, liver enzymes and several other markers. Attributing a change to a compound while losing weight is confounded by design.

the trend line matters more than any single value

Disagree with reading anything into that. One value, one morning, and you changed two other things in the same window.
